the night sky without any instruments, so we don’t know exactly who discovered it.

Measurements Mass: 641,693,000,000,000,000,000,000 kg Volume: 163,115,609,799 km3
Density: 3490 kg/m3
Mars would sink in water, because it is rocky. Gravity: 3.71 m/s2
If you were 100 lbs on Earth, you would be 38 on Mars.

orbit the Sun. It takes 1.03 Earth days for Mars to
rotate on its axis.

Temperature The temperature range on Mars is -87 to
-5°C. This is colder than Earth generally is,
and very cold compared to the high temperatures in Florida.

Composition/Appearance Mars is a rocky planet. It has a red surface caused by iron
oxide (rust). It has volcanoes, canyon systems, riverbeds, cratered terrain, and dune fields.
Its internal composition is silicate rock, iron, and iron-sulphide.
Mars appears red, and is known as the Red Planet.

Weather Mars weather varies day to day. It is
generally dry, cold, and clear. Temperatures can change 110° in one day. There are dust devils and dust storms there. The carbon dioxide in the polar caps freezes and becomes dry ice in the cold season. Sometimes snow falls, but never rain. There is no evidence that the snow ever reaches the surface of Mars.

Moons Mars has two moons, Phobos & Deimos. Asaph Hall discovered them both in
1877.

Water Evidence suggests
that Mars once had rivers, lakes, streams, and even an ocean. Today the only water found on Mars is either frozen in the polar caps or underground.

If you went to Mars… The air is thin and made of mostly carbon
dioxide, so you couldn’t breathe. You wouldn’t be protected from the sun because
Mars has a thin atmosphere.

Something Special Higher mountains and deeper canyons
than any other planet. The largest canyon would stretch from
Los Angeles to New York City. Has the solar system’s biggest volcano,
Olympus Mons, which is 3 times bigger than Mt. Everest.
